Compared with the prior art, the 360 DEG holographic projection device has advantages of reasonable design, simple structure, low cost and good imaging effect.

Description

360 degree holographic projectors
Technical field
The utility model belongs to the projector equipment field, especially relates to a kind of 360 degree holographic projectors.
Background technology
Holographic technique is to utilize the interference and diffraction principle to record and reproduce the technology of the real 3-D view of object.Different with other three-dimensionals " image ", hologram provides " parallax ".The existence of parallax make the observer can by all around and the difference image that moves up and down to observe image-as have really object there.
Current stereoprojection formula realizes by the polarisation of light principle, and spectators can only see corresponding polarized light image by every eyes of polaroid glasses, thereby produce stereo perception in visual system; This stereoprojection requires very high to the polarizability of screen; Also has in addition laser three-dimensional line holographic projections technology, principle is scanned the individual point in certain limit with multiple laser, thereby formation stereopsis, real 3D during due to the arrangement of scanning each point, the image therefore formed is also real 3D, laser beam beats on a locus, personage's image has just appearred without foundation, see it is all three-dimensional from any angle, but that this technology exists is high to environmental requirement, the problem such as relate to that technical bottleneck, cost are high, complex structure, imaging effect are poor.
Summary of the invention
For the deficiencies in the prior art, problem to be solved in the utility model is to provide a kind of simple in structure, cost is low, imaging effect is good 360 degree holographic projectors.
The technical solution of the utility model is:
A kind of 360 degree holographic projectors, comprise projector and projection tower tool, described projection is placed on light tight plate with the bottom of tower tool, described projector is located at the below of described light tight plate, described projection is stitched together and is formed hollow structure by a plurality of projection plates with the tower tool, described projection plate is light-passing board, and the light source that described light-passing board and described projector send is the mirror image structure.
Described light tight plate is provided with black coating.
Described light-passing board is provided with the line holographic projections film.
Described light-passing board is isosceles trapezoid, and a plurality of described isosceles trapezoid light-passing boards are stitched together and form the inverted pyramidal structures of removing the pinnacle part.
Described light-passing board is arc, and a plurality of described arc light-passing boards are stitched together and form the spherical structure that removes top and bottom.
Described line holographic projections film is located at the outside of described light-passing board.
Advantage and the good effect that the utlity model has are: change the single mode that presents picture of prior art, produce three-dimensional aerial mirage phantom, can also make mirage phantom and performing artist produce interaction, the performing effect that generation is made us shaking; The utility model compared with prior art, has the advantages such as reasonable in design, simple in structure, that cost is low, imaging effect is good.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1-projector, 2-light source 3-light tight plate 4-imaging region 5-light-passing board
Embodiment
Below with reference to the accompanying drawings embodiment of the present utility model is described in detail:
As shown in Figure 1, a kind of 360 degree holographic projectors, comprise projector 1 and projection tower tool, described projection is placed on light tight plate 3 with the bottom of tower tool, described projector 1 is located at the below of described light tight plate 3, described projection is stitched together and is formed hollow structure by a plurality of projection plates with the tower tool, and described projection plate is light-passing board 5, and described light-passing board 5 is the mirror image structure with the light source 2 that described projector 1 sends.Owing to adopting technique scheme, change the single mode that presents picture of prior art, produce three-dimensional aerial mirage phantom, can also make mirage phantom and performing artist produce interaction, the performing effect that generation is made us shaking; The utility model compared with prior art, have advantages of reasonable in design, simple in structure, cost is low.
Described light tight plate 3 is provided with black coating.Prevent reflective and affect the effect of projection.
Described light-passing board 5 is provided with the line holographic projections film.Guarantee that figure is more clear.
In the present embodiment, described line holographic projections film is located at the outside of described light-passing board 5.
Described light-passing board 5 can be isosceles trapezoid, and a plurality of described isosceles trapezoid light-passing boards 5 are stitched together and form the inverted pyramidal structures of removing the pinnacle part.
Described light-passing board 5 can be also arc, and a plurality of described arc light-passing boards 5 are stitched together and form the spherical structure that removes top and bottom.
Principle of work of the present utility model:
The image-forming principle of 360 degree holographic projectors of the present utility model is: the first step is to utilize principle of interference to record the object light-wave information, and this is shooting process: subject forms the object beam of diffuse type under laser irradiation; Another part laser is mapped on holofilm as the reference light beam, with object beam, stack produces and interferes, position phase and the amplitude of each point on the object light wave are converted to the intensity spatially changed, thereby utilize contrast and interval between interference fringe that the full detail of object light wave is recorded.Record the egative film of interference fringe after the handling procedures such as development, photographic fixing, just becoming a hologram, or claiming hologram; Its second step is to utilize diffraction principle to reproduce the object light-wave information, this is imaging procedures: hologram is just as the grating of a complexity, under coherent laser illumination, the diffraction light wave of the sinusoidal pattern hologram of one bracing cable record generally can provide two and resemble, i.e. original elephant the (claiming again initial image) and conjugate image.The image stereoscopic sensation of reproducing is strong, has real visual effect.Every part of hologram has all recorded the optical information of each point on the object, therefore its every part can be reproduced the whole image of the original in principle, can also on same egative film, record a plurality of different images by multiexposure, multiple exposure, and can show respectively without interfering with each other.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
